if there are no more nodes.

The next Node

Exceptions
TYPE_ERR
In case XPathResult.resultType
is not UNORDERED_NODE_ITERATOR_TYPE
or ORDERED_NODE_ITERATOR_TYPE
, an XPathException
of type TYPE_ERR
is thrown.
INVALID_STATE_ERR
If the document is mutated since the result was returned, an XPathException
of type INVALID_STATE_ERR

var xpath = "//div";
var result = document.evaluate(xpath, document, null, XPathResult.ANY_TYPE, null);

tagNames.push(node.localName);
}
document.querySelector("output").textContent = tagNames.join(", ");
